It's known problem. Such crash usually occurs when sK1 canvas is out of screen and tries refreshing. But compiz for sK1 is not required. This bug will be fixed in 0.9.2 version because it depends on canvas reimplementation.

It's known problem. Such crash usually occurs when sK1 canvas is out of screen and tries refreshing. But compiz for sK1 is not required. This bug will be fixed in 0.9.2 version because it depends on canvas reimplementation.

I am using enlightenment window manager and it implements virtual screens or desktops.

I was in the same screen where I started sk1 from an xterm window command line and sk1 did flash up on the screen for a VERY short period of time before dying and returning the error I posted.
